Testing Engineers International have certified the Fan 50 Plus Pins to UL372 and UL353 specifications as they pertain to the RV Industry.

With absolutely no changes, these are the same boards Dinosaur has been selling for years.

The Fan 50 Plus Pins is designed to replace the new Suburban and Atwood/HydroFlame Fan Control boards as well as maintain backward compatibility with the Fan 50 Plus Pins, and UIB Fan Control boards which have been available since 1994. This board can also be used to upgrade older furnaces to add the Fan Control feature.

The basic purpose of a Fan Control Ignitor Board is to shut the fan motor off if the board fails to sense a flame after the third ignition try. Thus, battery drain is reduced and the needless blowing of cold air is eliminated.

The Fan 50 Plus Pins, after shutting the fan motor off, will wait for 1 hour and repeat the whole sequence again before permanent shut down.

*Note:The fan control feature MUST BE USED for proper operation of the board. Fan control boards should not be used in DuoTherm 900 series furnaces that have the thermostat in the ground circuit. DuoTherm furnaces can be rewired to move the thermostat from the ground side of the circuit to the positive side of the circuit so that the Fan control features of the Fan control or Fan 50 Plus Pins board can be used.

Propane is an explosive gas! Ignitor boards should be installed by trained service technicians.

The Fan 50 Plus Pins works with the following manufacturer's part numbers:

My Suburban NT34SP all of a sudden just fizzled out on me & outside temps were in the low 20's to high teens! Ordered The Fan 50 Plus Pins & when I got it, the hardest part of installing it was removing & replacing the furnace into it's compartment. When compared to the OEM board, the Dinosaur is less expensive & has a longer warranty. Now we're warm agin!

I received the board promptly and the install was easy. The board works well and seems to be a quality product. I use American RV Company for all of my online purchases because they are a trusted source of quality products for my RV.
